## Using Feature Based Measurement

The Feature Based Measurement (FBM) method is an optional feature in PC-DMIS. FBM functionality is only available if your PC-DMIS license is programmed with the Feature Based Measurement module.

FBM offers collision-free measurement of any dimension in a measurement routine.

Mini routines provide the user interface that enables you to execute a measurement routine that you create with the FBM method. Sub mini routines provide the facility to create the structure to measure tool-based, cell-based, and operation-based features from the measurement routine.

FBM is useful in situations where you want to do the following:

- Create a measurement routine for a complete, manufactured part and still be able to use the same measurement routine to measure the part, or a single feature, after each operation

- Quickly measure only selected features; for example, you may want to change tools on a fully-automated manufacturing line

- Run a partial measurement routine

FBM has two parts:

1. Creating a measurement routine with FBM

2. Executing a measurement routine with FBM
